High, reproducible RNA yields. Total RNA was purified in duplicate from different amounts of Jurkat cells using the RNeasy Plus Mini Kit or a similar kit from Supplier AV. Real-time RT-PCR assays for β-actin were performed (40 cycles). The lower CT values with the RNeasy Kit demonstrate greater RNA yields. With the kit from Supplier AV, no transcript was detectable in RNA purified from 102 cells. 
Effective tissue genomic DNA removal.

Total RNA was purified in duplicate from various mouse tissues (10 mg per sample) using the RNeasy Plus Mini Kit or kits from other suppliers. Real-time PCR assays for c-jun were performed to determine the amount of DNA contamination in the purified RNA.
RNeasy Plus procedure.

A short workflow enables RNA purification with genomic DNA removal in less than 25 minutes.
Effective cell genomic DNA removal. Total RNA was purified from Jurkat cell samples (1 x 106 cells per sample) using [A] the RNeasy Plus Mini Kit, or [B] an RNA purification kit with integrated genomic DNA removal from Supplier AV. Duplicate real-time RT-PCR assays for β-actin were performed with (+RT) or without (-RT) reverse transcriptase. The -RT curves demonstrate that RNA purified using the RNeasy Plus Mini Kit was virtually free of genomic DNA.
Array-ready RNA. Total RNA was purified in duplicate from 1 x 106 HeLa cells using the RNeasy Plus Mini Kit. cRNA was prepared from the duplicate RNA samples (3.5 μg each) using the GeneChip IVT Labeling Kit. The cRNA samples (15 μg each) were analyzed on GeneChip Human Genome U133A probe arrays. The scatter plot shows the correlation between the two samples (Pearson correlation coefficient [r] is 0.996). Red: gene present in both samples; Blue: gene absent or marginal in one sample; Yellow: gene absent or marginal in both samples.
